How many genes are in the salmon genome?
This is similar to the number of genes (37,206) that were found for the Atlantic salmon [34], but lower than the number of genes (46,585) found in the rainbow trout genome [57].
How many base pairs are in salmon DNA?
16665 base pairs
The complete sequence of the Atlantic salmon (Salmo salar) mitochondrial genome has been determined. The entire sequence is 16665 base pairs (bp) in length, with a gene content (13 protein-coding, two ribosomal RNA [rRNA] and 22 transfer RNA [tRNA] genes) and order conforming to that observed in most other vertebrates.
How many chromosomes do Atlantic salmon have?
The European Atlantic salmon generally has 29 pairs of chromosomes and 74 chromosome arms whereas it has been reported that the North American Atlantic salmon has 27 chromosome pairs and an NF of 72.
How big is the human genome?
6.4 billion letters
A real human genome is 6.4 billion letters (base pairs) long.
What are the characteristics of salmon?
The Atlantic salmon is a slender and graceful fish whose Latin name means “the leaper.” Its distinctive characteristics make the Atlantic salmon easy to recognize. It has a small head, blunt nose, small eyes, and a mouth that gapes back below its eye. The mouth contains a row of stout, conical teeth.
How many DNA sequences are there?
The number is essentially infinite. Using an estimate of mutation frequency of around 2 x 10^-8 per base pair per replication event, we get 60 novel mutations in every living human being. There are 7 billion humans, so we know that some 420 billion different variants are possible.
How much of our DNA is junk DNA?
Our genetic manual holds the instructions for the proteins that make up and power our bodies. But less than 2 percent of our DNA actually codes for them. The rest — 98.5 percent of DNA sequences — is so-called “junk DNA” that scientists long thought useless.
How big is the fruit fly genome?
180 Mb
The Drosophila genome is ∼180 Mb in size, a third of which is centric heterochromatin (Fig. 1).
Does salmon have scales?
Most fish, including salmon, have a layer of scales covering their skin. Scales are small, hard plates, like fingernails, that cover the body for protection. The scales overlap to form a flexible armour plating to protect from predators and bruising.
What is the salmon life cycle?
It comprises six stages: egg, alevin, fry, parr, smolt, and adult. Salmon are anadromous, meaning they spend their entire life in the ocean, but migrate to rivers and streams to spawn. In simple words, they are born and die in freshwater rivers, but remain in the sea till the onset of adult stage.
